Fig. 2.

T3 and T4 serum concentrations in cows grouped according to IGF-I concentration. T4 values were logarithmic transformed (logT4). The table shows results of the mixed-model ANOVA with a covariance structure matrix spatial power and the random effect [SP(POW)+RE]. Data are expressed as the last square means ± SE. Significant differences (p < 0.05) between the two groups at individual time points are indicated with the letters a^* and b. Statistical tendencies (p = 0.06) are indicated by letters c^† and d. BIC: Bayesian-Schwarz criterion.
